dev, I did what you said and that fixed the error I was getting with the IPN panel in the admin tool. So I set up the IPN module to use the paypal sandbox for some testing. All of my transactions go through and the money shows up in my account, but none of the IPN information gets passed back to my site.
I tried using the IPN test panel and I get this error when I hit the 'Test IPN' button:
FATAL ERROR: register_globals is disabled in php.ini, please enable it!
I'm thinking that since it is the catalog/ipn.php file giving this error that it is probably related. I already used the register_gloabls patch on osC. Is there one for the IPN module? I tried talking my host into just enabling it but... I don't think that is going to happen.
Thanks for your help. =)
